ANDREW F. MILLER, OF GEARFOSS, MARYLAND SLIDING GATE.

SPECIFICATION forming part of Letters Patent No. 225,295, dated March 9,1880.

Application filed November 15, 1879.

To all whom it may concern:

Be it known that I, ANDREW F. MILLER, of Oearfoss, in the county ofWashington and State of Maryland, have invented certain new and usefulImprovements in Sliding Gates; and I do hereby declare that thefollowing is afull, clear, and exact description of the invention, whichwill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, whichform a part of this specification, and in which Figure l is a sideelevation of my improved gate closed. Fig. 2 is a similar view, showin git partially opened. Figs. 3 and 4 are vertical sections taken throughlines 00 w and y g respectively; and Fig. 5 is a detail view of the gatelocking and unlocking mechanism.

Similar letters of reference indicate corre sponding parts in all thefigures.

. This invention has relation to sliding gates; and it consists in theimprovement hereinafter fully described, and particularly pointed out inthe claim.

In the drawings, A is the gate, which may be of any suitableconstruction, and is provided with the end pieces, a a. Two of the slatsof the gate, denoted by A A, extend through and back of the rear endpiece, (0, their ends being united by two vertical slats, b I), betweenwhich are journaled the rollers c c.

B B are two uprights, between which the gate slides, and which areconnected on top by a cross-head, B. O is a post set back of theparallel uprights B B, and connected thereto by a slotted rail, D, theend post, E, up.- rights B, and post 0' being all in aline with eachother.

, Between the parallel uprights B B is journaled a roller, 01, uponwhich one of the gate slats rides in opening or closing the gate; andthe rail D passing between the two rollers c c, it follows that the gateis supported solely by the slat or rail D and roller 61, so that it willslide free of the ground, both in opening and closing.

The locking device consists of a bifurcated spring, F, which is securedupon the rear end slat, a, with its ends projecting into the slot 6 inthe rail D. This slot is provided with a double series of notches, f f,so that as the gate slides upon rail D, in opening or closing, thebifurcated ends of spring F will slip into these notches, and therebyhold the gate firmly in place in any given position. To release thespring, two cords, g g,'may be employed, the ends of which are fastenedin opposite ends'of spring F, and pass through staples h h and k i tothe front part of the gate, so that by pulling these cords the ends ofspring F are released, and the gate may he slid forward or backward toopen it or close it at will.

Having thus described my invention, 1 claim and desire to secure byLetters Patentof the United States- The combination, with the slidinggate A A A la b and horizontal slotted guide-rail D, having notches ff,of the bifurcated lockingspring F and its operating-cords g'g,substantially as and for the purpose herein shown and specified.

In testimony that I claim the foregoing as my own I have hereto afiixedmy signature in presence of two witnesses.

ANDREW F. MILLER.
